Crumpets, beer and chicken: All the things we're running out of thanks to the heatwave

Crumpets have become the latest casualty of the carbon dioxide crisis, with the UK set to face a shortage as food and drink producers are forced to halt production.

Bakers firm Warburton's, the country's largest producer of the popular snack have halted production at two of their four plants due to the shortage, with CO2 supplies also running low at its other sites.

Beer producers are struggling with the high demand posed by the World Cup and hot weather

Carbon dioxide is used for the packaging of crumpets, giving it a longer shelf life and preventing mould.

Why is there a CO2 shortage?

The current carbon dioxide shortage is a result of an unusually high number of factory closures, which produce the gas as a by-product of the fertiliser industry.

But being as farmers don't require as much fertilisers during the summer months, ammonia plants often close down for essential maintenance.

The UK has been the worst hit by the closures (which has also affected Europe as a whole), with only one of its plants currently operational.

What else are we running out of?

As well as food packaging, carbon dioxide is also used to carbonate soft drinks and beer, and to stun farm animals.

As such, the crisis has increased pressure on supplies of beer, Coca Cola, chicken and frozen food.

The demand for beer has been particularly high in demand thanks to the World Cup and the hot weather, putting an added strain on producers.

There is also a lack of the Cypriot cheese halloumi available on shelves this summer, with producers struggling to keep up with the demand from British consumers.

Although this might seem like a rare occurrence, such problems are actually not unusual.

It was only in February 2018 that takeaway giant KFC had to temporarily close down hundreds of outlets when it ran out of chicken.

All of these shortages happen because of the decisions made regarding a company’s supply chain.

With KFC, a few months before the shortage, the company had decided to switch its logistics service provider from Bidvest to DHL. The result was a massive disruption to the supply chain at the time of the changeover.

Six years ago, rival firm Burger King made the exact same decision with very similar consequences.

The message to organisations who provide consumers with food and drink should be made loud and clear: start caring about your supply chain like it matters.
